A local pizza place claims that they average a delivery time of 7.32 minutes. To test this claim, you order 11 pizzas over the next month at random times on random days of the week. You calculate the average delivery time and sample standard deviation from the 11 delivery times (minutes), and with the sample mean and sample standard deviation of the time (minutes), you create a 95% confidence interval of (7.648, 9.992). (delivery time is normally distributed) a. What...

An airline claims that its flights are consistently on time with an average delay of at most 11 minutes. It claims that the average delay is so consistent that the variance is no more than 92 minutes. Doubting the consistency part of the claim, a disgruntled traveler calculates the delays for his next 25 flights. The average delay for those 25 flights is 23 minutes with a standard deviation of 17 minutes. Assume α = 0.05. Is the traveler disputing...

NBC claims that viewers spend a daily average of 175.1 minutes watching their content. An advertiser wants to verify this and conducts a poll of 10 random viewers who claim to watch NBC. The poll showed that this group spends a daily average of 163.3 minutes watching NBC with a standard deviation of 15.7 minutes. Use a 0.025 significance level to test the claim that the daily average amount of time NBC viewers watch NBC is at least 175.1 minutes,...

Two math teachers (Kelly and Thomas) in the same school were teaching the same grade level. Kelly had 30 students and Thomas had 31. At the end of the year, both classes took a test and results were normally distributed with Kelly’s students (78, 10) and Thomas (85, 15). Using a 10% significance level, determine if there is a difference in the teaching quality of the two teachers. a.What is the Null Hypothesis b.What is the Alternative Hypothesis? c.Is this...
